THE INFLUENCE OF THE INTENSITY AND THE FREQUENCY ON THE ENHANCED IONIZATION BEHA VIOR OF MULTIATOMIC MOLECULAR IONS IN THE INTENSE LASER FIELDS
光强、频率对强激光场中的多原子分子离子增强电离行为的影响

The enhanced ionization(EI) behavior of multiatomic molecular ions is studied in intense laser fields by the numerical solution of time\|dependent Schrodinger equation with the symmetrical splitting of the short\|time exponential propagator and fast fourier transformation(FFT).The influence of the intensity and the frequency of the laser on EI is given.With the laser frequency increasing,the criticla value of bond length for EI decreases and the ionization probability decreases too.The ionization probability increases with increasing laser intensity.The EI disappeares when the intensity reaches a certain value.
